Don't get caught outgunned, step up to the 6.8mm
The new #1 AR15 deer and hog cartridge
AR Performance as a parts manufacturer selling direct to the public is committed to providing the best practical performance in the AR15 platform at a decent price. Our premium barrels out perform most so called "match grade" barrels. Better exterior ballistics, terminal performance, accuracy, velocity and long life are all possible with finely tuned chambers and high performance hybrid 5R rifling in Melonite treated 4150 CMV barrels. 4150 barrels are twice as strong as some stainless. Our 6.8 barrels are the number one choice. We machine the strongest AR15 9310 alloy bolts made and several efficient muzzle devices.
The AR10 never looked this good
7lb Nexgen MSR in 308 and 260 Rem.
Can't give the old DPMS LR 308 away? This is the answer!
The next generation of 308 sized platforms. Finally an option for those too heavy to carry DPMS LR rifles sitting in the back of the safe. For years many have said they wish there was an AR12. A rifle bigger than an AR15 but without the weight of the AR10. In 2009 I designed a "12" more or less. A 7lb 16" barrel 308 or 260 Rem. rifle is possible. Standard 308 Pmags can be used in DPMS style LR 308 lowers. These Nexgen uppers can be built to fire any 308 based cartridges. The new DPMS GII is a very close copy of these uppers.
We will sell kits which include an upper receiver, carrier, bolt and barrel. In addition to that you will need an AR10 charge handle, your choice of any AR15 handguard/rail, gas block, gas tube, AR10 firing pin, AR15 cam pin and cotter, flash hider or comp.
16" 308 and 18" 260 versions avail. Jan 2015. Rifle above weighs 7lbs 10oz as shown with a fluted 20" 6.5x47 barrel.
We will produce the billet receivers, carriers(BCGs), bolts, barrel extensions and barrels. All of those parts are specific to the Nexgen and will be sold in the beginning as sets, other caliber barrels later. All of those parts should run $850. That is apx what you can buy the same DPMS LR308 parts for. You should be able to buy the rest of the upper parts including a $180 rail and have a complete upper for $1100. Those like me who have a LR lower sitting half around not being used because it is so heavy can build a usable high performance rig for $1100. A complete rifle should cost apx 14-1600, considerably less than any LMT, Larue, POF, LWRC or Knight some of which sell for almost $4000.
This is more than just a light 308 AR. By removing the reciprocating weight...heavy carrier, the system does not need to be over-gassed as much to move the carrier. The carrier starts moving later than the AR10 system resulting in less movement and better accuracy. These rifles do not feel like the old clunky AR10 or DPMS LR series rifles. They feel much more like an AR15. Most competitors 308 rifles still have that huge carrier that rocks your whole body when it cycles.
No we aren't the cheapest but we use billet receivers, 9310 alloy bolts, carriers and barrels extensions. Melonite treated 4150 11595E barrel steel. High performance 5R rifling with a low land to groove ratio. With us it's all about performance.

A BETTER 6.5 in a 6.8 MOUSE TRAP
I have designed a chamber 41mm long based on a 6.5 bullet in a 6.8SPC case. 6.8 bushing dies are used to neck down the case then the cases are trimmed to 1.620". That lets the popular long high BC 6.5 bullets like the Hornady 100Amax, 123gr Amax and SST, Barnes 100 and 120 TTSX, Nosler 120NBT and Lapua 100gr Scenar to be loaded to the cannelure or ogive without modifying mags. I believe our SIX5 design corrects all the problems with the wider PPC case used in the Grendel/264. The bolts are stronger, extractors are stronger, several mag brands to choose from. Hornady, Federal, SSA/Nosler and Remington makes brass for $35-50/100. There is no need to hold the max pressure down to 52,000 PSI to keep bolts from breaking, the SIX5 runs at 58,000PSI max. The hoop stress around the chamber is less due to the cartridge being smaller diameter than the Grendel. In addition we use only 4150 11595E gunbarrel steel to increase the strength around the chamber over the weaker 416R stainless. A normal AR15 lower receiver may be used, some steel mags like PRI allow loading to the same length as the Magpul SIX8 mags. The performance will be apx the same as the Grendel/264 with 123 gr bullets and faster with 100 and lighter bullets.
Coming winter 2014
264 LBC / 6.5 Grendel barrels and bolts
Due to popular request we are producing more 18 & 20" 6.5 Grendel / 264LBC barrels.
18" barrels are in stock.
These barrels shoot either 6.5 Grendel or 264LBC ammo. It is the same cartridge with a different name.
Possibly the strongest most durable 4150 11595E Melonite treated 6.5 barrels made. The barrels have 5R rifling with a 1 in 8.5" twist rate. The chamber is perfect for loading the 123 Amax and SST to 2.295 or the 120 Noslers just a little shorter. The 100grTTSX, 100 Amax, 100gr Nosler and even Hornady factory 123 Amax and SST shoot under 3/4 MOA.
There is a long history of 7.62x39 and 6.5 Grendel bolts breaking. They are without a doubt the weakest link.
To combat the problem we have done 2 things. 1-Our 9310 alloy bolts have a larger radius at the root of the lugs and the lugs are .002 wider than mil spec. This extra attachment adds apx 24% strength to the lugs.
2- For those that want the ultimate in bolt strength these barrels will be available with an optional 800 series bolt and extension. The 800 series bolts are the strongest 264LBC/Grendel bolts made. With a design strength of 35720 lbs they are more than twice as strong as most 6.5 Grendel bolts. They have proven since 2009 they can withstand the 6BRX run at 60,000psi. The Lapua Grendle case will rupture before the bolt breaks as long as the receivers are square and all lugs carry the thrust evenly.
IN THE WORKS
The 6.5BRX in an AR15 is coming back summer 2015
The 6.5 fans have requested I bring back the 6.5BRX. It is apx 200fps faster than the 6.5 Grendel.
With the right bullet it can be one of the flattest shooting AR15s made right behind the 6mmBRX.
6.5 Grendel bolts- improved design apx 24% stronger than ANY other Grendel bolt.-In Stock on bolt page
5.56x42- Based on the 6.8 case. The ultimate AR15 varmint cartridge, performance close to the 22-250
Allows using longer bullets than the BHW version.
30 Herrett- based on the 6.8 case. The real semi-auto 30-30. 250 fps faster than the 300 AAC BLK.
Allows using longer bullets than the BHW version
The Ultimate AR15 hunting cartridge
Available in limited quantities for the AR15, a full power .277 caliber cartridge capable of propelling 120 gr bullets over 2900fps and 130gr 270 bullets to 2800fps out of AR15 20" barrels. That is as fast as factory 260 Remington ammo. It is based on the 6.5x47 Lapua case. Shortened Hornady 6.5 Creedmoor cases, Win 308 cases or 6.5x47. 6.5x47 Lapua cases work best and last longer.
Whidden Gunworks custom micrometer resize dies for the 270AR, avail through our store.
2nd batch of barrels expected May 2015
The 6.8X43 was developed as an improved CQB cartridge by the 5th Group Special Forces. The devasting performance combined with the AR15 makes it the #1 choice of hog and deer hunters .
It has apx 80% of the performance of the 308 in a much lighter platform.
We have designed a 5 groove hybrid rifling similar to 5R with a low land to groove ratio to increase the bore area and lessen bullet deformation which leads to better accuracy. We have found that our 5R Melonite QPQ barrels consistently produce 60-90fps more than most SPCII 10 and 11 twist 4 groove barrels with the same loads. Hornady's 110gr HPBTs reach 2600fps from our 16" barrels and normally shoot under 3/4" groups at 100yds. With better shooters groups are near 1/2" so they shoot better than some high dollar stainless barrels and most match grade 5.56s . Hornady's 120gr SST and Federal's Fusion 115gr work very well on deer and hogs. With handloads it is possible to push a 100gr Nosler to 3000fps from a 16" barrel, nothing else with a 16" barrel comes close to the performance of a 6.8. ammo finder http://www.gunbot.net/ammo/rifle/68spc/
The 4150 11595E steel Melonite(QPQ) treated barrels we sell will last twice as long as stainless barrels and the final finish meets or exceeds stainless steel corrosion resistance. Stainless barrels .980" in diameter do not meet the 2:1 burst/hoop strength safety ratio required by the firearms industry standards in anything larger than the 5.56. We only use the stronger 4150 11595 E barrel steel in all of our barrels.
The 6.8SPCII and 6.8x43 we use shoot the same ammo including SSAs Tac loads and Wilson Combats ammo uses the same size dies, only the throat in the chamber is different.
